SHEET 1 [IF 2 ATTORNEY GRILLER BRIEF SUMMARY OF THE INVENTION Thisinvention relates to a griller for roasting meat, fish and the like.Conventionally, a griller has been used as an appliance for roastingmeat, fish and the like. But in conventional grillers, the upper partthereof is open, directly whereunder a heating body, such as gas burnersand the like, is positioned, and which meat or fish is put on a metallicnet or iron plate or is otherwise positioned to be grilled or roasted bythe heat of the gas burner.

Therefore, water, oil, grease and the like oozing from the meat, fishand the like normally drops on the heating body situated directlythereunder to burn or evaporate them, resulting in creating a great dealof smoke, flame, and vapor and in polluting, in case for indoor, notonly the air in the room but also the whole room by the smoke and vapor.

So, in order to rectify these defects, there has been provided a grillerwhich makes the said water, oil, grease and the like not drop on theheating body by covering it with heat-resistant glass for receiving thefoods, but in this case, defects were found such as having to do thecleaning of the glass as well as decrease in the heat efficiency and/orfrequently the glass may crack or produce other problems.

One object of this invention is to provide a griller having an extremelygood heat efficiency and allowing water, grease and oil from the foodnot to drop on the heating body contained therein.

And in a conventional griller, a heating chamber has been formed by theheating body equipped under the case whereof and by the side wall of thecase, which causes the heat of the heating chamber to heat the caseitself, resulting in lowering of heat efficiency owing to loss of heatto be used for the thing grilled or roasted, and moreover, a man workingnear the case having been unable to continue work for suffering a painby the heat, sometimes has had the experience of burns by contactingwith the case.

Another object of this invention is to permit only a small quantity ofheat to be conducted to the case as well as to remove the possibility ofburns from the case and to concentrate efficiently the heat at theopening part without the heat being taken up by the case itself. And afurther object of this invention is to obtain a griller with the openingpart thereof changeable suit ably in width, thereby enabling the grillerto be used for various purposes.

DETAILED DESCRIPTION OF INVENTION Referring now to the drawings, thereis illustrated a description on a recommendable embodiment of thisinvention.

The numeral 1 indicates a case, formed of metallic, thin plate likestainless steel, nearly all over the upper surface whereof an openingpart is made. There is vertically dropped from the brim of an oven plate3 facing the said opening part a reflecting plate 4, at the lower partwhereof a heating infra-red gas burner 5 is positioned forwardly of avertical line or plane X dropped from the edge of the oven plate 3facing the opening part, with the lower part thereof being secured to asustaining plate 7 fixed to the side wall of the case 1. The saidreflecting plate 4 is shaped to extend obliquely forwardly and connectsthe upper part of the infra-red ray gas burner to the brim of the oven.plate 3 so as to correspond to the heat emitting direction of theinfra-red gas burner 5. 8,8 indicate guide rails formed in a letter Lshape by beinding respectively the upper ends of the right and the leftside walls of the case 1. Said guide rails 8,8 are made to sustainwheels 13,13 put thereon which are suitably secured to sustaining plates12,12, to which a reflecting plate 10 positioning an infra-red ray gasburner 9 is secured. The reflecting plate 10 is contoured oppositely tothe plate 4.

Guide rails 8, 8 may be formed by projecting a piece of the plate inwardof the side walls ll, 11 at their upper ends. The said infra-red ray gasburner 9 is positioned on the outer or rear side of a vertical line orplane Y dropped from the brim of a loading or support plate 14 which isprovided at the upper end of the reflecting plate 10. The plate 14 is ofthe form of the letter L. The gas burner 9 is positioned to pointobliquely upwardly toward the opening 2. At the lower part of the burnersupport a screening plate 15 extends vertically downwardly.

The reflecting plate 10 is obliquely positioned and connects the upperend of the infra-red ray gas burner 9 to the brim of the loading plate14 so as to correspond to the heat-emitting direction of the gas burner9.

Numeral 16 indicates a handle with a knob 17 and an elbow 18 is providedat the lower end of the handle, and a connecting rod 20 passes through ahole 19 made in the side wall 11 of the case 1 to connect to the elbow18. The rod is loosely held in the side wall 11 of the case 1 between abushing 6 fixedly fitted on the connecting rod 20 and the elbow, therebythe handle 16 and the connecting rod 20 are united and sustained in afreely movable way by the shape of the hole 19. The connecting rod 20 isformed, for example, nearly in the shape of the letter L, having at theupper end thereof a pin 21 projectively extending therefrom. The pin ismovably engaged in an oblong hole 22 made in one of the sustainingplates 12. Thus by turning the handle 16 through an arc the wheels 13,13 are moved on the guide rails 8, the reflecting plate 10 positioningthe infra-red ray gas burner 9 is moved to the right or the left (FIG.2) to vary the size of the opening 2. The connecting rod 20 being, asshown in FIG. 4, connected to one of the sustaining plates 12 throughthe pin 21, it or the pin 21 may be made to movably insert into anoblong hole 22 formed on both of the sustaining plates 12, 12 byextending it or the pin 12 to the other sustaining plate 12 is desired.

The tumable angle range of the handle 16 corresponds to the movingdistance by wheels 13, on the sus taining plates 12 which are controlledand determined respectively at the rear end thereof by hitting againstthe folded end 24 of the back wall 23 of the case 1 and at the front wayby being restricted by the movement of the pin 21 within the oblong hole22, but it may be equipped with a stopper-like projection on therespective guide rails 8, 8 thereby to obstruct the movement of thesustaining plates 12, 12 The case 1 has therein the reflecting plate 4positioned at a suitable interval to the front plate and a ventilatingspace 26 formed between them. Adiabatic materials, for example, likeasbestoes 27, 28 or other insulating means are pasted to or suitablypositioned spaced from the backs of the reflecting plates 4, 10,respectively.

Oblong interstices are formed in or above the front plate 25 and ovenplate 3 respectively as ventilating holes 29, 30 and may be replaced bymany circular holes or by only one ventilating hole without forming ahole 30. Numeral 30 indicates a loading plate which is fixedly securedto the oven plate 3 and formed to the same height as that of the loadingplate 14 described above.

Numeral 32 indicates a water basin or shield positioned by hanging theprojective part thereof on the loading plate 14, but the said basin maybe omitted if desired. Numeral 33 indicates a opening which is formed inthe front side plate 25 of the case 1 and has a knob 34 secured to aslidable receiving tray 35 for collecting water or liquids by means ofguides 37, 37 secured to the folded brim 36 at the opening and to theside walls ll, 11

The said receiving tray 35 is positioned adjacent the lower ends of thesustaining plate 7 and of the screening plate 15. 38, 38 indicateconventional gas cocks equipped with ignition devices operativelyconnected to the gas burners. Now, if an explanation is to be made on amean for using and the action of this invention, it as follows; byopening gas cocks 38, 38 equipped with ignition devices, infra-red raygas burners 5, 9 are ignited and heat emitted from the infra-red ray basburners 5,9 is released and directed to reach directly the opening part2, or the heat which is diffused up and down in the heat-emittingdirection is reflected by reflecting plates 4, 10 with a part thereofrising along reflecting plates 4, 10 and the other part rising withheating the air at the lower part of the opening part 2, causing both ofthem to concentrate heat at the opening part 2 at any rate. Thereof,fish, vegetable and the like on skewers hung between the loading plates31, 14 or otherwise supported thereon can be roasted, grilled, orbroiled and fat, water, grease and the like dripped therefrom drops intothe receiving tray 35 without touching the infra-red ray gas burners 5,9, hence generating no smoke, thereby resulting in enabling one tobarbecue even inside as well as outside the building.

When a wide opening part is needed according to the largeness of thebarcecue, or as in the case of using an iron plate to support meat, orfood by turning the handle 16 by the knob 17 wheels 13, 13 begin to rollon the guide rails 8, 8 to move the reflecting plate 10 and theinfra-red ray gas burner 9, causing to widen the opening 2. Andmoreover, even when heated, the reflecting plate 4, which is positionedat a suitable interval to the front plate 25 and the heat being screenedby a layer of asbestoes 27 and the ventilating hole 26 being provided,therefore, the heat is released outside by way of the said ventilatingpart 26 and the ventilating holes 29 or 30, causing no undesirableheating of the front plate 25. Thereby the operator will not be burnednor to work in the heated air.

An explanation has been made on a griller, wherein one 9 of theinfra-red ray gas burners 9, moves simultaneously when the opening 2widens or narrows has been made. However, if the size of the opening 2is not to be changed, a griller having the loading plate 14, thereflecting plate 10 and the screening plate 15 under the infra-red raygas burner fixed to the side walls 1], ll of the case 1 can also beused.

The various parts of the griller can be secured together or engagedtogether in any suitable manner. A conventional gas supply means (notshown) connects to the gas cocks 38.

Other heating units than the gas burners can be used if desired.

The gas cocks 38 suitably connect to the gas burners.

While one complete embodiment of the invention has been disclosedherein, it will be appreciated that modification of this particularembodiment of the invention may be resorted to without departing fromthe scope of the invention.
